Benefits of technology
The present invention is a downhole paraffin melting tool, which includes a heating element for melting paraffin, a battery pack for powering the heating element, and a control board for controlling power output. The tool has a cutting head with multiple cutting edges and is designed to be easily connected and disconnected from the housing and battery pack. The battery pack is capable of delivering a high amount of power to the heating element and can control the temperature reached by the heating element. The invention is convenient for use in downhole operations, such as drilling and well servicing, where it can be adapted for specific needs and operating conditions.
Problems solved by technology
The accumulation of paraffin within the production tubing of a working oil well is a major problem experienced throughout the petroleum industry.
The process of removing tubing from a well bore, the insertion of a servicing tool and return of the tubing to put the well back into production is both time consuming and expensive.

Abstract
A downhole paraffin melting tool is provided, comprising a heating element housing having a cutting head and a heating element disposed within the heating element housing. A battery pack is disposed within a battery pack housing, wherein the battery pack is operatively connected to the heating element. A control board is disposed between the heating element and the battery pack, wherein the control board is adapted to control power delivered from the battery pack to the heating element. A top sub is connected to the battery pack housing, wherein the top sub includes a retrievable member. The battery pack, delivering power to the heating element through the control board, is adapted to maintain a predetermined temperature of the heating element during operation.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This nonprovisional application claims the benefit of priority to U.S. provisional application, Ser. No. 62 / 161,662, filed on May 14, 2015.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicable.THE NAMES OF THE PARTIES TO A JOINT RESEARCH AGREEMENT[0003]Not applicable.INCORPORATION-BY-REFERENCE OF MATERIAL SUBMITTED ON COMPACT DISC[0004]Not applicable.BACKGROUND OF THE INVENTION[0005]1. Field of the Invention[0006]The present invention relates to oil well servicing and more particularly to a method and apparatus for removal of accumulated substances including paraffin deposits along an oil well tubing, and more particularly to such methods and apparatuses that do not require power through a wireline.[0007]2. Prior Art and Background[0008]Petroleum crude oil contains many constituents that can precipitate from the crude as it moves from the producing formation to the wellhead. One of those constituents is paraf...
